提出了一种新的有限元数值模拟方法来研究电磁在随机掺杂细金属线和短金属线的介质材料板中的传播。在许多标准教科书和已发表的论文中描述的FEM方法被适当地修改，以考虑到细金属线和短金属线的存在。利用这种改进的有限元方法，估计了放置在x波段矩形波导中的材料板（随机掺杂细金属线和短金属线的均匀介质板）的透射和反射特性。将估计结果与CST微波工作室模拟工具的数值结果进行了比较。
A new numerical simulation method using the finite element methodology (FEM) is presented to study electromagnetic propagation through a dielectric material slab doped randomly with thin and short metallic wires. The FEM approach described in many standard text books and published papers, is appropriately modified to account for the presence of thin and short metallic wires. Using this modified FEM approach, the transmission and reflection characteristics of a material slab (homogeneous dielectric slab doped randomly with thin and short metallic wires) placed in an X-band rectangular waveguide are estimated. The estimated results are compared with the numerical results obtained using the CST microwave studio simulation tool.
